Create struct bdev_handle that contains all parameters that need to be passed to blkdev_put() and provide bdev_open_* functions that return this structure instead of plain bdev pointer.
v1->v2: Add new bugfix 8bd90b6ae785 ("erofs: fix NULL dereference of dif->bdev_handle in fscache mode"). Fix the comment of cd34758c5238 ("block: Remove blkdev_get_by_() functions"). v2->v3: Fix the comment of acb083b55597 ("block: Use bdev_open_by_dev() in disk_scan_partitions() and blkdev_bszset()").
